Though the RISC-V platform is meanwhile widely accepted for embedded systems application, its instruction set architecture (ISA) currently still supports only two basic BMIs.We introduce ten advanced BMIs for the RISC-V ISA and implemented them on Berkeley's Rocket CPU [1], which we synthesized for the Artix-7 FPGA and the TSMC 65nm cell library. Our RISC-V BMI definitions are based on an analysis and combination of existing x86 and ARMv8 BMIs. Our Rocket CPU hardware extensions show that RISC-V BMI extensions have no negative impact on the critical path of the execution pipeline. Our software evaluations show that we can, for example, expect a significant impact for time and power consuming cryptographic applications.}}, author = {{Koppelmann, Bastian and Adelt, Peer and Müller, Wolfgang and Scheytt, Christoph}}, booktitle = {{29th International Symposium on Power and Timing Modeling, Optimization and Simulation (PATMOS)}}, title = {{{RISC-V Extensions for Bit Manipulation Instructions}}}, doi = {{10.1109/PATMOS.2019.8862170}}, year = {{2019}}, } @inproceedings{24060, abstract = {{In diesem Artikel stellen wir eine Methode zur nicht-invasiven dynamischen Speicher- und IO-Analyse mit QEMU für sicherheitskritische eingebettete Software für die RISC-V Befehlssatzarchitektur vor.

DecodeTree is a code generator included in QEMU that can generate the program logic for extracting and decoding opcodes and operands from a formal instruction list of the target architecture. This enables the structured implementation of just-in-time compilations to guarantee that the QEMU implementation meets the ISA specification. As such, we completely replaced the existing RISC-V RV32GC and RV64GC implementations by DecodeTree generations in the next official QEMU release, which is expected in spring 2019.
